Abstract (en)
[origin: EP1398807A2] The invention provides a solid electrolytic capacitor of a configuration having a metal plated layer in a cathode part in order to prevent a decrease in the conductivity by oxidation of a conductive polymer and to realize a high reliability. Also there is provided a configuration in which a cathode part of the solid electrolytic capacitor includes a first metal plated layer and a solderable second metal layer.
[origin: EP1398807A2] The capacitor has an anode part e.g. aluminium foil (27) with a lead wire extracted from an end of a metal piece having an oxide film (29) and a solid electrolyte with a conductive polymer layer (31) formed on the oxide film. A cathode part includes a conductive material layer (33) formed on the polymer layer and a metal plated layer (35) over which is a solderable metal layer (37).
